Open Source Algorithms - Is There an Obligation to Make Them Open Source?

If algarithms are involved in the decision, is there an obligation to make them open source? I think that everybody sol of agrees that transparency is really important here. But then simultaneously, i thinkit by releasing and making everything open source, then i think that you are going to stifle innovationt. It's just vast. And i just don't think it's realistic that atually you can ask the community at largereally to be able to take on that load....
